 The single-cylinder hydraulic cone crusher has attracted the attention of many ore processing enterprises for its extremely efficient crushing performance. So in the face of various equipment use environments, what problems will generally occur in single-cylinder hydraulic cone crushers? What should we do when we face these problems?

    1. Dust prevention
    The external fan of the dust-proof system of the single-cylinder hydraulic cone crusher is affected by the external environment, and the filter element is seriously blocked, and the wind cannot be directly observed. The air pressure is often low due to the inability to replace the filter element in time, the dustproof effect is poor, and the lubricant is replaced frequently And other problems; if the filter element is replaced regularly, it will cause unnecessary waste. For this reason, it is planned to add a pressure control valve on the dust-proof air outlet to replace the filter element in time and effectively control the air pressure.
    2. Cooling problem
    For example, the lubrication systems of two crushers in a factory are in a small space about 2m below the ground level, and poor ventilation has a great impact on the air cooling system. Due to the lack of air circulation, although cooling facilities such as fans and ice cubes are added, the air cooling effect is still not ideal, so the protection temperature has to be increased, which is very unfavorable for the crusher. To completely solve the problem, we can only start from several aspects such as the displacement of the cooling fan, the civil engineering transformation of the lubrication system, and the transformation of cooling methods.
    3. The adjustment of the discharge outlet
    At the initial stage of replacement of the new liner, the discharge port can reach the set value of about 13m; but after the liner is worn to a certain extent, the discharge port is expanded to about 18mm and cannot be adjusted down; when the liner is worn to the later stage , The discharge port reaches about 20mm, basically no crushing effect. For this reason, measures have been taken to adjust the eccentricity from the original 50mm to 40mm. After taking this measure, although the throughput of the crusher has been reduced, the discharge opening can be basically maintained at about 13mm, which is beneficial to increase the qualified particle size in the discharge and reduce the return of ore.
